Abstract Sex hormone-binding globulin (SHBG) in the blood is a major determinant of bioactivity for key sex steroids such as testosterone and estradiol. Low serum levels of SHBG have been associated with obesity, polycystic ovaries and metabolic syndrome, and other states associated with hyperandrogenemia. A 9-year, 6-month-old girl presented with a history of peripheral precocious puberty and aggressive behavior. The patient’s SHBG level was remarkably low for her age, at less than 5 nmol/L [reference range for a girl with a bone age of 10 years, 73 nmol/L (SEM= 10)](1). Upon genetic and protein analysis, the patient was found to have a homozygous missense potentially pathogenic variant in the SHBG gene (c.554 C>T, p.P185L); her parents were asymptomatic heterozygote carriers. Laboratory investigations supported the possible involvement of this genetic alteration in the patient’s phenotype. Various analyses of this variant support its pathogenicity, although the exact mechanism remains unclear. In conclusion, we present a genetic SHBG variant in the homozygote state that may have been associated with gonadotropin-independent precocious puberty in a young girl.

Objective. To study primarily on the effect of acupuncture on breast Tanner stage, serum sex hormone level, and TCM symptom scores in girls with peripheral precocious puberty (PPP). Methods. 19 eligible patients diagnosed with PPP received acupuncture intervention for 12 weeks, twice a week for 12 weeks, 24 sessions of acupuncture treatment in all, and then follow-up for 12 weeks. The primary outcome was the change in serum luteinizing hormone (LH) level, follicle-stimulating hormone (FSH) level, and breast Tanner stage at 12-week treatment and 12-week follow-up. Serum estradiol (E2) level and TCM symptom scores were also assessed. Results. Nineteen patients with peripheral precocious puberty were treated with acupuncture. After the 12-week acupuncture intervention, the serum LH level, breast Tanner stage, and TCM symptom scores decreased significantly compared with baseline (P<0.05); the serum FSH and E2 level did not change significantly after the 12-week treatment (P>0.05). After the 12-week follow-up, breast Tanner stage and TCM symptom scores decreased significantly compared with baseline (P<0.05), and there was no statistical difference between serum sex hormone (LH, FSH, and E2) level and baseline level (P>0.05). During the period of acupuncture treatment, no side effects or serious adverse events occurred. Conclusions. Acupuncture is effective in regulating the hormone level and controlling early development process. It may be a viable alternative to the treatment of peripheral precocious puberty in girls. However, further randomized controlled trials are needed.
